Trouble copying audio file – until rdd-copy

I had trouble copying a audio file (wav) from a CD to my computer – the copy process was always getting stuck at exactly the same point 153MB in. And it didn’t matter whether I was using sound-juicer or nautilus. The answer was to install rdd (sudo apt-get install rdd). rdd copes with errors by supplying blanks (assuming multiple careful attempts to read the data have all failed) rather than halting.

The required command was rdd-copy src dest. But what to supply as src? I tried /media and similar but no luck. The final answer was ‘/run/user/1000/gvfs/cdda:host=sr0/Track 3.wav’. But how to find it? Just drag the file from nautilus to the terminal and see what is displayed there. The following worked even though it took a long time to get the file:

rdd-copy '/run/user/1000/gvfs/cdda:host=sr0/Track 3.wav' /home/g/Desktop/track3.wav
